They say heat up the allen before you insert it and it should break the bond but like you I couldn't get it off either. I was able to purchase just the bolt with the pillow separately so I didn't have to buy an entire assembly.

1) With the firing assembly removed from the marker and the bolt taken off, unscrew the 'metal remains' from the inside of bolt using the needle nose pliers. It may take a a slight bit of muscle but it shouldn't be too hard because it's only blue loctite holding it in.

2) With the metal piece removed place a drop of blue loctite on the thread of your replacement pillow and use the needle nose pilers to screw it back into the bolt. Be sure not to grip to tightly as you'll rip the pillow; just hold it tightly enough to get it to screw in

3) Give the loctite a couple minutes to dry and put your firing assembly back togeather and put it back in the gun and your done!

I've heard that there are a couple different versions of the pillow bolt. Mine shot out of my mummy and I have a replacement one with the threads like the one in the pics. Will that one fit on my bolt or are there really different versions of them making me look for the matching part?

i talked to a guy at blast he said there working on fixing the shooting out pillow problem when i got my new pillow it had flear glue on the outside probably for more support hope i dont shoot it out again (3x )
